Abstract

We have developed the advanced onboard antennas for High Throughput Satellite (HTS). They are three types of the antennas utilizing Ka-band frequencies to aim in-orbit verification by the Japanese Engineering Test Satellite 9 (ETS-9). First antenna is the fixed multi-beam antenna (Fixed MBA) employing the miniaturized and integrated feeder unit to enable dense allocation of multi beams for improvement of spectrum efficiency. Second antenna is the Digital Beam Forming antenna (DBF-ANT) to enable flexible beam shape. Third antenna is the common communications system antenna (CCS-ANT) transmitting broad beam which has beacon transmission function etc.

Abstract

The trans-Pacific high data rate (TP-HDR) satellite communications experiment was proposed at the Japan-U.S. Cooperation in Space (JUCS) Program Workshop held in Hawaii in 1993 and remote high definition video post-production was demonstrated as the first phase trial. ATM-based 45 Mbps trans-Pacific link was established in the first phase, and the following experiments with 155 Mbps was planned as the phase 2. This paper describes the experimental network configuration and project plan of TP-HDR experiment phase 2. Additional information is provided in the original.

Abstract

Abstract Background We previously reported the usefulness of the αGal epitope as a target molecule for gene therapy against cancer. To induce cancer cell specific transcription of the αGal epitope, an expression vector which synthesizes the αGal epitope under the control of a promoter region of the human telomerase reverse transcriptase (hTERT), NK7, was constructed. Methods NK7 was transfected into a human pancreatic carcinoma cell line, MIA cells, and telomerase-negative SUSM-1 cells served controls. Expression of the αGal epitope was confirmed by flow cytometry using IB4 lectin. The susceptibility of transfected MIA cells to human natural antibodies, was examined using a complement-dependent cytotoxic cross-match test (CDC) and a flow cytometry using annexin V. Results The αGal epitope expression was detected only on the cell surfaces of NK7-transfected MIA cells, i.e., not on naive MIA cells or telomerase negative SUSM-1 cells. The CDC results indicated that MIA cells transfected with NK7 are susceptible to human natural antibody-mediated cell killing, and the differences, as compared to NK-7 transfected telomerase negative SUSM-1 cells or telomerase positive naïve MIA cells, were statistically significant. The flow cytometry using annexin V showed a higher number of the apoptotic cells in NK-7 transfected MIA cells than in naïve MIA cells. Conclusions The results suggest that αGal epitope-expression, under the control of the hTERT-promoter, may be useful in cancer specific gene therapy.

Abstract

A 47-year old woman was referred to our hospital with nausea, vomiting and the loss of body weight. Pelvic computed tomography and magnetic resonance imaging revealed an invasive bladder tumor on the left lateral wall, accompanied with calcification. Laboratory examination revealed marked hypercalcemia (20.6 mg/dl) and elevated serum parathyroid hormone-related protein-intact (29.9 pmol/l), which was apparently produced by the tumor. Treatment with pamidronate and colloid infusion resulted in normocalcemia. Anterior pelvic exenteration was performed. Histopathological diagnosis was transitional cell carcinoma > adenocarcinoma, G3, pT4pN2M0, stage IV. She died of cancer 7 months postoperatively.
